Since we have \(161\) employees, the 81st one is their median since we exclude 80 data from the least number and 80 data from the greatest number after we put the numbers in an ascending order.
Since we have \(29 + 58 = 87\) from the first two top rows, the 81st one should be in \(20-29\).
Therefore, A is the right answer.
